From Rise: The Vieneo Province
You can convince an NPCs to accept a proposal of yours, depending on just how beneficial (or detrimental) the proposal is for the NPC and how the NPC views you to begin with. The better the proposal and the better your relationship with the NPC, the more likely the NPC is to accept your offer. If you succeed, the NPC accepts your offer.
Convincing others with Persuasion generally takes at least 2 full minutes. In some situations, this time requirement may greatly increase. A rushed Persuasion check can be made but you take a –10 penalty on the check.
Optional, but not recommended because retries usually do not work. Even if the initial Persuasion check succeeds, the other character can be persuaded only so far, and a retry may do more harm than good. If the initial check fails, the other character has probably become more firmly committed to his position, and a retry is futile.
